The fallout V from a volcanic explosion (measured in kilograms per square kilometer) depends on the distance d from the volcano and the time t since the explosion began, so V equals f (d comma t ). Time is measured in hours and distance is measured in kilometers. What are the units of fraction numerator d f (10 comma t )over denominator d t end fraction?

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12
